PTFE braided packing with graphite is woven of graphite PTFE yarn twisted through a mixture of PTFE dispersion resins and fine graphite powder, with a moderate amount of heat-resistant lubricant. Apart from its corrosion resistance, it has thermal conductivity and self-lubricating properties, and is suitable as dynamic sealing inconditions with media flow of high Linear velocity (about 16m/s).

Application conditions:

1) Max. working temperature: -75 ~ 280oC

2) Max. working pressure: 2.5Mpa (rotary pump)

Max. working pressure: 8Mpa (reciprocating pump)

Max. working pressure: 15Mpa (valve)

3) pH value: 0 - 14

4) Linear speed: 0 - 12m/s(rotary pump)

Linear speed: 0 - 2m/s(reciprocating pump)

Linear speed: 0 - 2m/s(valve)

5) Cross Section: ≥1/8" ~ ≤3"(3X3—75X75mm)

6) Density: 1.65 ~ 1.75g/cc

Regular package: 5 or 10kg/roll

Special package is also available as requested.

Warm tips:

We can use the GORE fiber from USA to make the similar packing with better sealing effect and longer usage life.
